Call User made Python modlue from Matlab

Hi,

I am having trouble calling a python module (wirtten by me) from matlab. I saw simarl questions and aswer but no onw I found was useful to be. Here are the details:

I have installed Python 3.8 on Windows via the official python website.

In matlab I set the path to the python executable using pyenv:

py = pyenv('Version', 'C:\Users\giaco\AppData\Local\Programs\Python\Python38\python.exe');

Since my module is in another folder I add this folder to the python search path using the function py_addpath (found on the matlab file exchange)

py_paths=py_addpath('C:\Users\giaco\Documents\PROJ_WORK_Thesis\');

The path seems to be added correctly infact py_paths is:

 py_paths =

  7×1 cell array

    {0×0 char                                                                 }
    {'C:\Users\giaco\Documents\PROJ_WORK_Thesis'                              }
    {'C:\Users\giaco\AppData\Local\Programs\Python\Python38\python38.zip'     }
    {'C:\Users\giaco\AppData\Local\Programs\Python\Python38\DLLs'             }
    {'C:\Users\giaco\AppData\Local\Programs\Python\Python38\lib'              }
    {'C:\Users\giaco\AppData\Local\Programs\Python\Python38'                  }
    {'C:\Users\giaco\AppData\Local\Programs\Python\Python38\lib\site-packages'}

But when I run my module as:

    the=py.thetae.thetae(r.pa, r.ta, r.rh);

I get the following error:

    Unable to resolve the name py.thetae.thetae.
    

Any suggestion on how to solve this?

Thanks in advance!

Try adding adding the path as:

insert(py.sys.path,int32(0),'C:\Users\giaco\Documents\PROJ_WORK_Thesis\');

Please verify the following points as well

1. A file called thetae.py exists in your 'C:\Users\giaco\Documents\PROJ_WORK_Thesis\' directory.
2. The file if exists has the function thetae defined in it.
